ATJTOMIATIC PISTOL.

Specification of Letters Patent.

Patented Sept. 13, 1910.

To all whom it may concern:

Be it known that I, CH'AnIEs PHILTBERT CM'IMENT, gun -1nuker, subject ofthe King of Belgium, residing at Liege, Belgium, have invented certainnew and useful Improvements in Automatic Pistols; and I do herebydeclare the following to be a full, clear, and em ct description of theinvention, such as will enable others skilled in the art to which itzippertains to make and use the some. v

The present invention relates to on auto inetio pistol of the fixedbarrel type, which is particularly designed so as to permit of somebeing readily opened and to render the different parts easilyaccessible.

Referring to the accompanying drawing Figure 1 represents the pistol inelevation, partly in section, and shown opened. Fig. 2 is on end view,Fig. 3 is a. plan. llig. represents in plan, the bolt separately. Fig. 5shows in side elevation, in plan and end view the rod which connects thebolt to the re-ection spring. Fig. 6 shovvs the ring or plug whichserves as an abutment for this spring.

The pistol consists essentially of the body or frame 1, provided at therear end and upon the upper side, with a block 2, :ietinsr us it 'guldefor the sides 3 of the bolt and us on abutmentfor the letter, when it isdriven lmclnvurd by t 1e recoil.

The bolt 4 is of a solid and heavy cons't-ruction as shown in l ig. d,and it is only recessed or slotted-out at the rear end, at 5, to allowof passing around the block 2. The casing 6, whose rear end is pivotedabout on axis 7 curried by the block 2, curries ut its forward end thebarrel 8, or is made in one piece with some. The casing (3 covers thebolt i, While the barrel 8 comes immediately iii-front of too latter 1).The barrel 8 is provided upon its \mdel'side with :1 projecting purluiul which is adopted to be engaged by a nose it) o! the triggerguurd ll. which pivoted utthe forward end, near the nose 1U, upon a pin 12carried by the body 1. This trigger guard ll is in the form of a springand 9 which engages in the body 1 hings '7.

carries at its free end a stud 13 which enga res, by a snap action, in arecess 14; formed in. the front of the body 1.

The elasticity of the spring ll m'eint-ains the trigger guard in placeand insures the engagement of the nose in the recess 15 of the lump 9 ofthe barrel 8; the latter is thussecurely held in position. By exertingu. slight pressure on the trigger guard 11 the stud 13 is disengagedtromthe recess 14, and allows ot' the casing 6 turning about the axis 7.

The reaction spring 16 isloeeted in the fore part of the casing i, abovethe barrel S. It hours at its rear end against a ring or plug 17, fixedin position by means of a. pin 18 passing through the walls of thecasing 6, and at its trout eud against the head 19 of a rod 20 whichextends through said ring 17. The spring 16, surrounds said rod Whichterminates. at its rear end, in e flattened head 21. This head 21 isprovided with an oval or other shaped slot 22 in which ongages, when thepistol is closed, a projection 23 carried by the top side of the bolt4:. This uri'eugculez'lt allows, by simply removing the pin l8. ofwithdrawing the rod 20 and the spring 16 without separuting the twoparts, which facilitates their usseuibluge. When the rod 20 is connectedto the bolt l, the reaction spring us tends cohstuutly to force thelatter forrxurd. I

win order to give to the hinge-pin 7 the necessary strength end to ullowoi it resisting, without lu-uulrugc, the shocks produced l'iy therecoil. the upper part of the block 2 is so formed at its forward end asto lit into the your torlied end of the casing (i and to constitutesuppleulculery points of connection (l igs .l and In the examplerepresented this is obtained by forming grooves ll iu the lateral Wallsof the block 9 in which corresponding parts :25 on the casing (5.011;,tire. The curved form given to the grooves Ll and ii .ib per-- mils otthe rotation of the ("using (a about the The tiring spring so is locatedat lhe reur of the body in a. member 17 cont'ormiug to the shape of therear end oi the curved ribs or projecting handle and capable of turningabout an axis 28 carried by the body 1 this spring 26 bears at one endagainst the part 2'? and at the other end against a plunger 29 by meansof which it acts upon the hammer of the firing mechanism. This member2'7, which enbetween the side walls of the body. 1, (Fig. is maintainedin its normal position by a flattened or recessed pin 30 which isadapted to engage with a corresponding recess 31 in the end of the part27. The pin 36 carries a small external lever 32 which the shooter caneasily operate when he wishes to turn the spring-carrier member 27 aboutits hinge to gain access to the parts constituting the firing mechanism.It is obvious that any other means can be employed for maintaining hepart 27 in its normal position. Said part 2'? preferably carries aspring 33 which acts upon the safety device 34 when the pistol is closedand which serves, in the known manner, to maintain this safety device inits two extreme positions.

Tilaving now particularly described and ascertained the nature of mysaid invention, and in what manner the same is to be performed, Ideclare that what I claim is:

1. in pistol, the combination of a body having a rigid upwardlyextending abutment, a sliding bolt engaging said abutment and limited inits reciprocations thereby, a casing pivotally connected with saidabutment and adapted to cover the bolt, and a barrel carried by saidcasing.

2. Ina pistol, the combination of a body having an upwardly extendingprojection, a sliding bolt mounted on the body and having a slot throughwhich said projection extends, apivotally mounted casing carrying abarrel and adapted to inclose the bolt, and means for securing thecasing in closed position.

3. In a pistol, the combination of a body, a sliding bolt, means on thebody for guiding and limiting the reciprocations of the bolt, a casingpivotally connected to the body at one end and carrying a barrel, saidcasing being adapted mvhen in closed position to cover the bolt, andmeans for securing the .asing in such closed position.

4:. In a pistol, the combination of a body, a sliding bolt mounted onthe body, a casing pivotally connected with the body adjacent its rearend and having a barrel formed integral therewith, said casing beingadapted to cover the bolt when in closed position, and means for lockingthe casing in such position.

5. In a pistol, the combination of a body, a sliding bolt mounted onthebody and limited in its movement by an abutment thereon, and a casingpivotally connected with said abutment and having a barrel formed into;therewith, said casing covering the bovhen in closed position.
